SPECIFICATION forming part of Letters Patent N o. 582,018, dated May 4,1897. Application led October 27, 1896. Serial No. 610,248. (No model.)

To @ZZ whom t may conoci/'7o.r

Be it known that I, JAMES I-IERVA JONES, a citizen of the United States,residing at Rockford, in the county of Vinnebago and State of Illinois,have invented certain new and useful Improvements in Flows, of which thefollowing is a specification.

My invention consists in forming a universal-joint connection betweenthe handle and moldboard, in forming a pivotal connection between theplow-standard and plow-beam, in forming a self-adjustable connectionbetween the handle and beam, and in providing sockets for the ends ofthe round near the top of the handle held in place by a rod extendingparallel with the round.

In the accompanying drawings, Figure l is a perspective view of a plowcontaining my improvements. Fig. 2 is a section in the lengthwisedirection of the handle. Fig. 3 is an isoinetrical representation of thesocket connection between the handle and plowbeam. Fig. 4 is anelevation of the connection between the plow standard and beam.

The plow 1 is of the usual construction, having a standard 2, connectedto a plow-beam 3. Handle-bars 4L and 5 are connected together, one barconnected to the plow standard and beam, and the other bar connected tothe moldboard of the plow.

The handle-bars are connected together by means of a brace 6, near theirlower ends, and a round 7 at their upper ends. This round has its endsseated in sockets S, and the sockets are placed against the inner facesof the handle-bars, having lugs 9, embracing the top and bottom faces ofthe bars. Arod 10, having its ends screw-threaded, extends parallel withthe round and passes through holes in the sockets and handle-bars,receiving a nut Il upon its projecting ends. In the old method largeholes are bored through the handle-bars and the ends of the round aredriven into these holes andsecured with pins. This construction makesthe round necessarily small at the ends, and the holes through thehandles so large as to weaken them and endanger both round and handleswhen the usual strain is brought to bear upon them.

Myinvention dispenses with the large holes through the handles andaifords means by which the ends of the round may be made as large asdesired for ample strength. The round and handles are also much moreeasily 5 5 repaired in case of breakage.

To the under face of the plow-beam is secured a bracket 12, having adepending proj ection 13. The upper end of the plow-standard 2 issecured to this projection by a bolt 6o 14, passing through the parts.This construction allows the bracket to conform to the under face of thebeam, to which it is attached at any varying angle at which the beam maybe necessarily attached. The old method is to furnish a bracket on whichthe beam rests, and which is rigidly fastened to the top of theplow-standard by riveting or welding, and it is necessary to place thebeam on the bracket in the position required and scribe and shave 7o itby hand to iit the bracket. This weakens the beam by cutting away a partof its thickness at a pointwhere it receives the most strain. It thusrequires a great deal of extra work and the beams cannot be made tointerchange with each other.

To the rear face of the moldboard is secured a clip 15, and to the endof the bar 5 of the handle is secured a hook 16, adapted V to engage theclip, thus forming av universal- 8o joint connection between the handleand plow, which allows the handle to be firmly fastened to the moldboardat any desired angle. In the old method a bracket or ledge is boltedrigidly to the moldboard, and the handle, after its angle to themoldboard is determined, is shaved or bent to conform to the bracket. Notwo moldboards are exactly alike inv shape, as they twist or spring intempering. Consequently the fitting of a handle 9o to a plow in such acase cannot be done by machinery, orbe duplicated or interchangeablework, but m ust be done by hand or scriberule.

The bar 4: of the handle has a connection 95 with the plow-standard andmoldboard by a bracket 17.

The rear end of the plow-beam, next the bar 4 of the handle, has asemispherical cavity 18, Within which is located a casting having a roosemispherical projection 19 and a hooked projection 20. This casting islocated against the inner face of the bar of the handle, the projectionoverlying the edge of the bar. Vhen the handles have been adjusted as toheight, a hole is bored through the bar 4 and plow-beam and a bolt 2lpassed through the parts and throughh the casting, and a nut placed onthe end of the bolt will clamp the parts together. This constructionallows a great range of adjustment of beam and handle in relation toeach other, as the casting can assume any position in the cavity of thebeam that is required, and any variation of angles is read ily provided.In the old method the beam and handle are temporarily clamped together,the beam scribed to the handle, and then shouldered and cut to theangles needed by hand to fit the handle. These angles are troublesomeand slow to make, and no other beam or handle can replace them withoutbeing fitted by hand.

In the old way of making plows herein described each part must have aseparate number stamped or marked thereon, so that the correspondingparts may be assembled at the end of shipment. There is often greattrouble in a large mass in Iinding the parts for this purpose. It isplainly seen that my improvements obviate all this dificulty and furnisha perfect duplication of parts.

I claim as my inventionl. In a plow, the combination of a moldboard, anda handle having a hook-and-eye connection.
